OMBINED SOCKET-COVER .AND"SHADE-HOLDER FOR ELECTRIC-LIGHT DEVICES.

Specification of Letters Patent.

Application filed April 26, 19-12. Serial No. 693,307.

To all whom it may concern: Y

Be it known that I, LAURITZ W. A nnR- SEN, a citizen of the UnitedStates, residing at Waterbury, in the county of New Haven electric lampto a socket by a shade ring and a plurality of spaced attaching screws.

These latter are very liable. to cause the shade to crack underinfluences of heat and expansion, and the shade ring is very liable tobecome bent, hence it is difficult to maintain the shade concentric withthe lamp, and the object of my invention is to overcome theseobjections.

In carrying out my invention, I provide a substantiallyconoidal cover ofsheet metal adapted to receive and set over a keyless lamp socket, andthe smaller end of this cover is apertured for the pipe of a chandelier,bracket or pendant, or for the electrio conductors alone. The larger endof the cover is formed with a circular edge and with a threaded collarsecured therein. "-T his collar receives a threaded sleeve which setswithin the rim of a shade or the glassware, while the circularedge ofthe cover comes outside the said rim, and thus the shade or glassware isheld in position with an even all-around bearing of an adjustable char'acter.

In the drawing, Figures 1 and 2 are elevations, illustrating the use ofthe device of my invention. Fig. 3-is a vertical section, through thedevice of my invention and of about full size, showing a socket and lampin position, and Fig. 4 is a detached section showing a detail bfmodified form.

' Similar letters and numerals of reference indicate similar parts inall the figures.

a represents the socket cover of conoidal configuration apertured at thesmall end and provided with an edge a of circular form in cross section.These parts are integral and the circular edge may be, and preferablyis, ornamented in any desired manner.

2) represents a collar fitting within the larger end of the conoidalcover and provided with a fiange'b by which the said collar is securedby solder or'rivets, or both, to the socket cover.

I have shown rivets at 2. I also provide a threaded sleeve 0' having aflange (1 represents the lamp socket, which in this particular device iskeylcss.

ductors from which, and the socket connected therewith, h are suspended.

Fig. 1 indicates that the device of my inthe socket cover and shade:ventionmay be connected to a fixture, that is to a bracket, electrolieror other electric fixture, "while Fig. 2 represents that the same mayswing from a ceiling or other support freely. Y

Fig. 3 represents the threaded collar 6, which is secured to the socketcover, as ex tending upwardly within the-socket cover, while Fig. 4represents this collar as reversed, in other words, extendingdownwardly, but my invention is not limited by the position of thethreaded Cover, as the same may occupy either position desired,according to the shade or glassware and the results to be obtained.

In connecting up the parts, as illustrated in Fig. 2, the electricconductors, connected to the socket, are to be passed through theaperture in the smaller end of the cover.

The rim of the shade or glassware is to be passed inside the circularedge of the cover and then the threaded. sleeve 0 is passed in side theshade or glassware and connected with the threaded collar so that theshade or glassware is held all around the rim with an even, firm but.not tight bearing.

Where the device of my invention is connected to an electrolier or abracket, it may occupy the inclined position shown in Fig. l

or it may han directly down or extend directly upward, as the same isadapted substantially to any position. Where the socket cover isconnected, as in Figs. 1 and 3, the pipe of a bracket or electrolier mayextendthrough the aperture inthe smaller end of the cover, and the coverat this end may come u agamst a bead or other stop, as shown, an aclamping screw -may pass through the stop, or a nut on the inside of thecover upon this pipe may be employed,

all of which fastening devices it is possible to use with the device ofmy invention. In such instance, a socket is connected to the :free endof said pipe, the electric conductors passing through the pipe Thedevice of my invention is particularly applicable to keyless sockets,asso many elec-- trical devices are employed nowadays where the light isoperated by a switch rather than at the lamp sockets, and this is oftennecessary because of the height to which the lights are placed or thenumber of lights grouped 011 a circuit.

In the device of my invention, the unstable shade ring is entirely doneaway with,

4 as are also the plurality of spaced attaching screws which are soliable to injure the shade or glassware, and in the device ofmy'invent-ion, the shade or glassware is held at the rim by an even,gentle all-around bear ing which readily permits of the expansion andcontraction of the shade or glassware without'liability of cracking thesame. I claim as my invention: l. A combined socket cover and shadeholder for electric light devices, comprising means removably co 'a'conoidal socket cover apertured at the smaller end for support, anenlarged lower portiomof the same to receive a shade, a supportingmember connected thereto, and ected with the said member in anadjustable relation, for secur ing-Ktheshade or glassware in position.

ware and the rim of the shade fitting within the largerlower end of thesocket cover.

. 3. A combined. socket, cover and shade holder for electric lightdevices, comprising a sheet metal socket'cover oflconoidalform-apertured at the smaller end fgirv connection with a means of support,and at; the larger lower portion provided-with an edge circularin crosssection adapted to receive a shade, a threaded fla ed collar receivedconcentricall with the 5 arger lower end of the socket cover and atlitsflange securely fastened thereto, and a threaded sleeve adapted to beconnected in an adjustable relation to the threaded collar, and saidsleeve having a flange which, with the circular edge ofthe socket coverreceives between them the rim of the shade or lassware and securely andadjustably hol the same.

Signed by me this 19th day of April, 1912.
